Combustion engine is obtain 2 each intake 7 exhaust 8. Response and are each 2 provided in the gas passage 5 air passage 6 also. Two of the intake passage 5 is obtained by branching a book passage having an opening toward surface of Sunda head 2 in Part Sunda head 2. Two exhaust passages 6 converge in da head 2 parts, are integrated into the passageway having an opening in a surface towards da de 2.

For injection into the surface, et al.

Hisen 2 is provided for the combustion.

It is sampled 5 is provided in the intake passage 5 before branching. It is sampled 5 is kept essentially fully open location. The control of Thailand grayed Li bet amount 及 of the intake 7 of the air volume of the combustion engine. However, for small to scan Tsu bets 5 to negatively generation of order to key studs negative intake passage 5 required for click. Scan Tsu door 4 providing Warini, even if the Yo corresponds to the case is required by providing a port-flops

The exhaust force 0 is the common rotary. Variation 9 to variably control the bets actuation of the intake 7, then with the O configurations described.

Here, the capital of the intake blanking 7, to a preparative amount of the intake 7. Further, a variable Gosuru that the maximum bets amount and bets amount of the variable, Do means the bets in the cycle of intake blanking 7.

Further, in this embodiment states provide only variation structure in the intake blanking 7 side, but the exhaust valve provided with a similar variation structure, Do fluctuation 9 I also control the phase of exhaust valve is in accordance with the operating condition, the intake 7 Li DOO 20 for changing the adversaries operation and its shift, and 2 Ru the advance if the retarded is, but Ru is constituted by combined see set.

It should be noted that this shift 20, with 2 Japanese Patent Office is the issuance and 00289303A and 02893, etc. in 2002.

Lift 2, have good and 22 in which are supported by the rotary resident in Rake Tsu preparative Presentation of da de 2 G ·, an eccentric force 23 fixed by this 22, the same racket towards the drive 22 a control 24 which is arranged in parallel with the drive 22 while being supported by the rotary standing, and Tsu mosquito a arm 28 swingably supported to the centrifugal force 25 of the 24, to Tape 42 disposed in 7 of the power It includes 3, a. Mound A arm 28 is Cua arm 26 connecting the vicinity of square through the connecting pieces 27, near the other of Ru is connected with the click 30 of via the consolidated 29. Via the click 30 connecting pieces 45 Ru is swinging force 3 connected.

22, Thailand croaker teeth is driven in centrifugal force 23 of the engine via the tie ring and.

Centrifugal force 23 has a circular, heart and heart only Fuse preparative it predetermined amount of the drive 22 Rutotomoni, this, is 26 a of Cua arm 26 to rotate ability.

Tsu mosquitoes A arm 28, centripetal force 25 to pass through the rotational capacity. Centrifugal force 25 hearts et eccentricity control 24, the dynamic center of Tsu mosquito A arm 28 varies in accordance with the control 24 location.

Power 3 is supported by the rotary resident in the drive 22, in the direction perpendicular Vita 3 relative direction of the drive 22, link 30 is connected to the connecting pieces 45. The power to 3 is given, 3 and C constituting the drive 22 concentric to, and Bill 3 Te drawing a 3 et above and line, it is made continuously. These 3 and 3 equivalents to Tape' 42 surface in accordance with the location of the swinging force 3.

That, 3 c as between Susa click a while bets of the intake 7 is, the swinging force 3 is in contact with the 3 b backlash Tsu preparative 42 swings, Li Tosuru the intake 7. It should be noted that between the La-flops of interference youth is provided between the between the Susa click between the door.

24 is configured whereas the Te by the lift patronized hydraulic activator motor 44 provided in the Yo rotates at a predetermined 囲内. The shift patronage oil pressure activator motor 44, that are controlled by the degree in preparative La 3 et.

Contact with this Doo 2, the drive 22 rotates, moves up and down is re Kua arm 26 Te by the eccentric force 23, which mosquitoes A arm 28 Te accompanied the swings 24 as a swing. This Tsu mosquito A arm 28 is oscillating force 3 ㍉ through the click 30, swinging force 3 swings. And good to use of the power 3, the tappet 42 is, the intake 7 Ghali Tosuru. Here, Li door

When patronage hydraulic activator motor 44 ging of the time the control 24, mosquito A arm 28 Dochu and is nondenaturing to change location of swinging force 3.

, The eccentric force 25 is to Ru in the upper location, the Tsu mosquito A arm 28 upwardly "as a whole, the third swinging force 3 is relatively upwardly pulled state and ing. Mari, the swinging force 3, Part 3 inclined in the direction Ru tappet 42 et away. Te, when the Te accompanied the rotation of the drive 22 is swinging force 3 swings, 3 c continues to contact the length between the tappet 42, the period of 3 to contact the tappet 42 is short. Te, becomes small as the total amount Li bets are to viz reduction up to the year al life.

Conversely, when the eccentric force 25 and Ru mended downward, re downward Lee as a whole Tsu mosquito A arm 28, a state of swing force 3 3 is depressed relatively lower. Mari, the swinging force 3, inclined in Konzuke direction thereof 3 to tappet 42. Te, 22 on the rolling Te companion swing force 3 is upon swinging, site tappet 42 contacts immediately shifts group 3 c et 3 b. Te, the amount of bets size becomes as a whole, or its expansion.

Runode is continuously change of heart force 25, Te companion to this, capital "" "" ".". . .

Also, DOO 2, bets and operation, both continue to expand at the same time, it is minified Rukoto.

2, a spool socket 46 provided in the driver 22 to, and the scan gasket 46 drive 22, and patronized A lipped data 43 Ru are Contact with relative rotation to a predetermined 囲内, Ru been made et. Spool 46 Thailand croaker also via a tie grayed bets rotates in class click synchronization. Patronage A Chi motor 43 is controlled by the issue of cement La 3 et. Depending on the movement of this control for the activator data 43, and the spool 46 drive 22 is relative rotation, there is a door heart angle is retarded. Mari, according to 2, unchanged with preparative entirely proceeds if the retarded. It can be obtained in this reduction also. The patronage activator motor 33, a hydraulic or electromagnetic type, an ability using Actinobacillus data format.

In Yo was mentioned, according to the variable 9, simultaneously preparative and operation's intake 7 is enlarged continuously can minified Rukoto, if the whole continuous manner without changing the preparative Susumu late it is the corner of Rukoto. Mari, can be independently controlled tie Jill tie grayed intake blanking 7. In the present state, to set the stage ring of the intake blanking 7 Yo follows.

G 3 is usually idle diversion shows an example of Thailand grayed of (up IG Tsu for fear, such idle rotation of ®), shows an example of Thailand grayed for 3B-flops IG Tsu ® stop.

Fuel costs required to Yo at the time of I-10 is in the high case, in order to little the port pin grayed vinegar, the Yo shown in G 3, the VC to temae to small the operation.

In this state, when the cooling air temperature is equal to degrees is high rise, up Ig Tsu ® occurs be.

In order to prevent the flop IG Tsu ® students, the Yo shown in 3, operates in increasing large of the, that the piston location that definitive intake VC to more retarded VC is changed Yo high-made than in the normal idle rotation It is Ru effective der. Reducing the air amount by high a Vist location in, a et capable low made.

While with the size and operate Yo 3 Then, acts accompanied Te in oscillating force 3 to the dynamic of the intake 7 becomes large. Therefore, sliding portions of the click 2 6, 28 30, etc. of the variable 9, for example of the centrifugal force 23 Kua arm with 26 of, for increased is large and problems of raw and dynamic. In particular, in the case di fights it is low in good time A stomach, a large amount the size of, also, sound and motion is felt significantly in the luck of both.

In order to suppress this sound and dynamic in allowance, for example, Yo shows three mark, it is necessary to smaller than for the flop IG Tsu ® Raw prevent the intake blanking 7.

However, in this stage it grayed, for close to the period the lower point of the intake 7, consisting of a high than Thailand grayed for-flops IG Tsu ® stop. For this reason, at this stage grayed, Do you child prevent flop IG ®.

Therefore, in order flop Ig Tsu ® stop is to small to scan 5 of, it is necessary to reduce the amount of intake air to further.

Door La 3 to control the intake 7 Thailand grayed scan Tsu door 5 of.

Note DOO La 3 consists of microphone pin having a central processing unit (P) read-only menu (R) La dam access menu (R) Beauty and out Kai data scan (a data scan). Configuration Rukoto the door La 70 in a few microphone pin are also possible.

G 4 is a blanking click view for explaining a control Thailand grayed control and scan Tsu door is cement La 3 to run. Cement La 3 is constant this control (example, if

) Repeatedly executed for each. Incidentally, shown in the figure is also the ability of bets la as virtual as Tsu bets, Do mean physical presence.

In B5, Te based on access to 5 classes click to 52 mag test shown in-2, and the like to find a constant to us was the target-up, calculating a target load is target value of the force of the internal combustion engine to. The troops grayed 52 as the target acceleration stage, the acceleration B53 as stage, the target air amount 54, is input to Jogenri data B55 of the Jogenri Tsu preparative calculation stage.

In Thailand grayed B52, goals, Te based on the issue of up IG ® emissions matter judgment B60 et al., To calculate the equal to target Thailand grayed to find the target stage grayed was constant. Thailand grayed is basically a tie ring for achieving a target load, if there is a risk of flops IG ® down students, the stage grayed in order to avoid this. The goal stage grayed you put in this Yo is input to the target B56. The acceleration 53, to round operation previously calculated during et al, calculates the acceleration of the target load, and inputs it to operation Jogenri jitter B55.

In the gas amount of B54, it issued a target air amount is a gas amount of achievement because the target load by, for example to find the Tsu-flops were pre-boss, this is the target scan Tsu door 58.

In Jogenri jitter 55, Te based on the target load and the target acceleration, and good to the control section later, calculates a Jogenri jitter for limiting operation, and inputs it to the target.

In B 56, calculates the Te based on the target forces grayed operation Jogenri data. That is, the target Thailand ranging et determined operation, targeting plus limited by data unless the operation. Is input to the variable activator data 57.

Flop IG ® emissions matter decision 60, as a means to detect the possibility of up IG ® occurs, to detect the conditions for the potential of-flops IG Tsu ® production. Flop IG ® Since occur with time by raising the cooling temperature is raised becomes easy, as the condition relating to the ability of the flop IG Tsu ® production, cooling Yutaka及 temperature and use Rukoto, the cooling temperature is the temperature to these are detected. And input the detected cooling temperature, the target pressure upper limit jitter 6, which corresponds to be sampled Jogenri Tsu capital calculation stages Yo to target Thailand grayed 52 predicates. It should be noted that the conditions for detecting here is not limited to the cooling Yutaka及 temperature, if the conditions that affect the flop IG Tsu ® students, even if the Yo to detect other conditions.

In 62, it detects that the time of the result variable activator motor 57 was line control Te group to the target, the detection result to da product calculation 63.

In Da product calculation 63, the Te groups Sunda calculated. 0 Da, but the static is Li da feed argument values ​​stroke volume in Da product found C in the intake valve VC, in fact, the intake start timing and, respectively C, Le respect intake valve VC cause.

This is before the intake valve C, because the dust reaches the intake pressure. The amount of time to the end of the actual extent to the valves VC of, Jin rolling speed is high Tokihodo, also bet amount is small Tokihodo of the sound is increased large Te big.

Therefore, the dust volume calculation 63 calculates a sexual et maximum bets of the intake 7. Then, the C-set amount proceeds as described above, determine the VC set CO S with reference to this-up Set-up to lame data gin rolling speed shift value, insert the intake valve C et C Set CS pull crank location was, and out as the effective C the extent intake is final.

If, care on C, et al of the deviation of the time when the extent intake to start is due to-back came in the gas by Oh La-flops.

In other words, it decreases the O rack et Te state 7 is opened Da Pressure et al, and pressure becomes later than intake top C, extent this point we intake is started. Small of da for opening product is small in the near, substantial exhaust come-back flow rate begins Oh wrap heart angle OC near et al., Which becomes the maximum. Amounts up period (C) Da is started extent actual al begins to decrease, as the di-rolling rate is high, also, Oh wrap (the case of Sunda Oh lap Te is big small indeed of sound weakens It increased by.

Therefore, the dust volume calculation 63, first, the intake VO intake

Enter the VC, to calculate your lap heart angle C. The body specifically, VO, and 7 of which is determined by the intake VC, Te group city known 8, Li preparative amount of sex to leave the cluster click angle in a match (YK as your lap heart angle OC.

The Deo La-flops heart angle versus Ru wrapped in C, and out to see the boss was up. When o wrap heart angle O CA is small enough (when in), o wrap O is Ru has a size characteristics.

In, di-rolling speed Oh wrap O as a lame data, the amount of up to Oh wrap heart angle OC et al effective C have set up-up, which was a C offset, determine the C set CO S refer to this-up , and out of the class-click location obtained by adding a C Seto CO S to turn La-flops heart angle OC as an effective C.

Then, intake, intake C, enter the effective C, the Sunda C in sexual et effective C of the intake 7, the same out with reference to-up, C, enter the effective VC, da C in the effective C , and out to see-up.

Only on this dialog goal scan Tsu door 58 beauty target pressure

6 is input to.

In as far the pressure jitter 6, calculates the atmospheric pressure on only for limiting the target pressure. Note that the intake pressure der Ru et al which the scan Tsu preparative limits the intake pressure means limiting the be sampled. Although the, the jitter value as far as on the target pressure is equivalent to a target scan Tsu door Jogenri jitter value.

Similar as long as on the care jitter B6 row calculation will be described later in details.

In the scan Tsu door 58, the target air amount, da product, to calculate the target scan Tsu door Te based on the jitter as long as the fine target care 圧上. That is, the scan Tsu preparative determined Te target air amount and the dust group, a plus limited by jitter as long as the target pressure and target scan Tsu bets. Is input to the scan Tsu door scan Tsu door patronage activator data B59.

Incidentally, hand methods of Te target air amount and the dust group to calculate a target scan Tsu TMG, law, for example, use Rukoto the Japan Patent Office is disclosed in JP2 7 2 5 78083 issued in 2007 method it can.

Next, the hand will be described jitter 6 as long as the operating Jogenri jitter 55 beauty target pressure.

G · 5 is a click diagram for explaining the control of operation Jogenri jitter 55 is executed. First, operation Jogenri jitter set 7 calculates the operating Jogenri jitter set amount to the target acceleration Te group 0 by-up search.

Here Ru use-up is provided shown in, that the target acceleration is at the operating Jogenri data set amount is under a predetermined value V, operating Jogenri jitter set amount in proportion to the acceleration large size on a given value Become.

In Jogenri jitter 72, Te group and this Jogenri jitter sets a target 5, sets the operating Jogenri jitter value by-up search. It provided with a sex show use Ru-up, in here. That is, constant operating Jogenri jitter value at a predetermined pressure, jitter value as long as the operation in proportion to the large loads between the predetermined et predetermined 3 increases, operation on a predetermined 3 Jogenri Ttachi again it serves as a constant is.

G · 6 is a diagram for hand described operation Jogenri jitter value. This figure is 0 Contact di indicate if flop IG Tsu ® raw fear such a, the characteristics of work rotation angle and the upper limit jitter value for the load. 6 is than satisfying operating suppressing dynamic, Run 2 is the for-flop IG Tsu ® stopped. Further, the load 2 under low, the upper load 2 high.

In Yo shown, actuating Jogenri jitter value, under the condition is satisfied actuated to keep the tolerance sound and vibration 5. In order to be required to be occurrence of sound and vibration, set this Yo an operation Jogenri data value. Since the fear that can prevent this condition in-flops IG Tsu ® is, in combination with control of the scan 5. Although in good to the control of the scan Tsu door 5 is under the output performance is a concern,

In Do not become a low-order problem request.

, On high for 3 constant operation 2 above that the order of up IG Tsu ® stopped. This in is increased the 泣出 force performance and combustion aspirated size of the variable structure is such conspicuous by Nalco is for suppressing requests noise and vibration is reduced. That is, without scan Tsu DOO control, only a further actuation by preventing flop IG Tsu ®, in order to avoid under the output performance. 9 2'm long as the for-flops IG Tsu ® stop but, in order to more reliably prevent the flop IG Tsu ®, is set to a value higher than the for-flops IG Tsu ® down stop.

That is, DOO La 3 in priority to the requests and keep within the permissible range sound and vibration than output performance, to avoid flop IG The combined use of scan Tsu bets control. In contrast, the output capacity in preference to the noise and vibration, Te'm only in further of working to prevent the flop Ig Tsu ®.

Preparative leading band in al load 3 sandwiching the (2) the high, to operate more than two for flops IG Tsu ® stop the limit to satisfy the request to suppress the noise dynamic, in proportion to the large the load of the engine Ru increase the 7 of Te. When the Tsu Toda stepwise switching at a predetermined load, scan Tsu preparative stepwise will be changed, preparative click ® Tsu occurs.

Increase of Runowa according to the load to operate at frequency leading to al load 3, is to prevent the Yo a preparative click ® Tsu.

If you set the operation upper limit Tsu capital value in this Yo, up IG in your under load

When the raw fear arises, Do not be operated Madeshi large. Since it is possible to prevent this in ®, to reduce the air quantity to prevent the flop IG Tsu ® under the control of the scan Tsu door 5.

On the other hand, if in your on the load 3-flops IG Tsu ® raw fear arises, it is possible to prevent the flop IG ® only in the large of the work dynamic, to avoid the bottom of the output to prevent the IG Tsu ® can.

Jogenri jitter set amount is an amount that moves the switching location, the actuation on data values. Since acceleration is large enough upper jitter value is large, the Yo shown in 1.7, as the target degree of size, becomes characteristic Yo more luggage et operatively becomes large. With to this Yo a custom, even more et operating Jogenri Tsu Since preparative value becomes big activator data for driving the variable 9 Hitoshigaa, it is possible to suppress output reduction in the transient.

Further, even de, and your spot de for shifting in this Doyori high Jin vehicle having an ability of automatic gearbox, the Yo states sports mode de is Ru is selected, that the degree of speed increases are predicted in the state, even in the Yo is set to operate on the jitter value. Thus, while avoiding instability due to control the degree of increase can be satisfactorily coercive operation. This case, the door La 3 to detect the traveling de by the issue of the transmission door cormorants, et al., And then to predict the degree of speed.

Incidentally, between the load-3, to load the name of the operating Jogenri jitter value becomes large frequency proportionally, load actuator actuation upper jitter value is 2 under 0, operating in load than the load 2 upper Ttachi as well as 0 2, operating a. The case, according to the operating Jogenri jitter set amount, working Jogenri jitter value is to the switching Waru load. With this Yo a disjoint structure, reduction of the calculation load, it is possible to focus Ryakuka per di.

In addition, even if the Yo working Jogenri jitter value in proportion to the load until the load et al increases. This case also, working Jogenri Ttachi there is cut-switched load so that the changes in accordance with the operating Jogenri jitter set amount.

G-8 is a diagram hand information on pressure jitter B6 of-4.

The calculation unit g, circle stroke Ve and La by da c and piston strike click Li Da, calculates the effective (Ve Vc.

In the above g2, air temperature and La, to calculate the c on a degree in point Ri by the ().

c X () K

In flop IG ® on pressure B93, calculated on c cooling and et, a flop IG ® on pressure P is flop Ig Tsu ® occurs such limit pressure by-up search.

Here Ru use-up may flop Ig Tsu ® on pressure P, a top horizontal axis c, are as defined for engagement with the flop IG Tsu ® on P on c for each cooling. Flop IG Tsu tio down on pressure P, the more the upper c is low high, also, the cooling temperature is Ru high enough low Do it. That is, they are the same on c, cooling high Hodopu Ig Tsu ® emission generates cyclones, et al., If the same, the upper c is Hodopu Ig Tsu ® is Ru shows the characteristic when generating low pressure al.

In pressure limit jitter 94 is flop Ig Tsu ® on pressure P intratracheal for suppressing under the () of the calculated target pressure limit jitter.

The body, the calculated and was use above Bg2, flop Ig Tsu on pressure P and et, a jitter P unless the pressure is the target pressure (2).

P Pc (2)

It should be noted, (2) is a formula in the case of the degree compression and adiabatic assumption, in this other, even if use of the cooling taking into account the formula.

The goal pressure on the jitter P issued in this Yo, the Yo described above, it is entered along with the target air amount and da c to scan Tsu door 58 of-4.

(2) According to the, up Ig Tsu ® on pressure P is about the size and effective small as the target pressure on unless data P becomes large. Who, working-out I see Li Da Vc is also large by effectively becomes small, effective is small indeed above c is low, up Ig Tsu ® on the pressure P is high.

Was it, the working size indeed, as long as the target pressure Tsu preparative P, jitter value as long as the Maris doo is large.

Incidentally, Do is not limited to states of the above facilities, even saying be can make like changes in surgically virtual 囲内 described in patent request for circumference.

For a description of the above, incorporating by reference the 2 0 8 0 2 capacity in Japan to filing 2008 6 30 days here.

On the availability of

In Yo above, this, because setting the operating Jogenri Tsu preparative value to limit the operating status et determined calculated et intake valve can be suppressed of the ability. Also, since the set the scan door Jogenri Tsu capital value corresponding to the work dynamic, is actuated limited sometimes with only Thailand grayed further such can avoid the flops IG Tsu ® production, the flop IG Tsu ® production by the scan Tsu bet your it can be avoided.

There is of this bright features are click-time to Yo follows
